Strap for Carrera Calibre Heuer 02T 45 Chronograph Tourbillon Titanium / Ceramic / Alligator / Mexico

The lug width of the TAG Heuer Carrera CAR5A8V.FC6377 is 20mm. This measurement is the distance between the two lugs (or spring bars) that attach the strap to the case, measured from centre to centre. It is a standard width for high-end sports chronographs and accommodates robust and characterful straps befitting a 45mm instrument.

Genuine alligator is the most aesthetically and constructively coherent choice. The rectangular grain pattern of the scutes, combined with the natural resilience of the leather and the patina that develops over time, reflects the Carrera's racing heritage perfectly. Valid alternatives include vegetable-tanned calf, which ages with amber character, and technical NATO for maximum versatility and practicality. FKM rubber remains the ideal solution for water sports.

To change the strap you will need a spring bar removal tool (or a precisely-sized pin) and small tweezers. Locate the two lateral spring bars that hold the strap to the case; gently push one bar with the tool and the strap will detach. Proceed carefully to avoid scratching the case. Insert the new strap by aligning the holes to the lugs and reattach the spring bars. Professional straps such as those from Milano Straps come with detailed instructions and telephone support.

Yes, any quality strap with a 20mm lug width is compatible. Verify that the spring bars of the new strap match the diameter of the original ones (typically 1.8–2.0mm). Milano Straps are crafted to precise specifications ensuring maximum compatibility and finish. If you choose a bespoke strap from the Casati Milano atelier, you will have absolute assurance of fit and personalisation.

A quality leather strap, under normal conditions, lasts 3–5 years before requiring replacement. Alligator and shell cordovan age exceptionally well and can exceed 7–10 years, developing a prized patina. Vegetable-tanned calf lasts approximately 4–6 years. Wear accelerates if exposed to constant moisture, perspiration or prolonged direct sunlight. Milano Straps include an 18-month warranty and can be refurbished through the Casati Milano atelier after the initial years of use.
